WebJul 27, 2024 · For the SO2 group, pathological changes, such as chronic bronchitis, local alveolar hemorrhage, and lymphocytes infiltration, were observed. The results of immunohistochemical analysis showed that CD19 + cells were decreased and CD3 + cells were increased in the SO 2 exposed group, compared with the control ( Figure 6 ). WebIn conventional air combustion, the reaction of CaCO 3 and SO2 occurs as follows: CaCO3→CaO+CO2 (Decomposition) (2) CaO+SO 2+1/2O2→CaSO4 (Sulfation) (3) The reaction of CaCO3 and SO2 is a solid−gas reaction. In general, the reaction rate and η are affected by temperature and atmosphere. Fig.1 shows calcium
WebThe synergistic effect between SO 2 and NO 2 was not observed on other mineral particles (such as CaCO 3 and CaSO 4) probably due to the lack of the surface reactive oxygen sites. The synergistic reaction between SO 2 and NO 2 on mineral oxides resulted in the formation of internal mixtures of sulfate, nitrate, and mineral oxides. WebCarbon dioxide/a gas is evolved; this forces its way out of the solid and breaks down its structure. What type of reaction is taking place during the heating process?
